Consumer Mains

  • Identification of cable cores.

  • Current carrying capacity.

  • Voltage Drop.

  • Aerial installation conditions.

  • Connection of wiring.

Switchboards

  • Location. e.g. Not in restricted location, access and egress.

  • MEN connection Intact.

  • Basic protection against contact with live parts. e.g. insulation and enclosures.

  • Fault protection (protection against indirect contact with live parts) by the use of automatic disconnection of supply. Check that the consumer mains have over current protection.

  • Protection against the spread of fire.

  • Protection devices installed and suitably rated for over-current protection, arc fault protection and discrimination.

  • RCD's installed on applicable circuits.

  • Isolating devices e.g. main switches.

  • Connecting devices. e.g. earth bar, neutral and active links.

  • Connection and fixing of wiring and switchgear.<br>

  • Identification and labelling of electrical equipment. e.g. switchboard markings and circuit identification

  • Protection against external influences. e.g. mechanical damage, effects of UV light.

Wiring Systems

  • Conductor Size. Check current carrying capacity and derating of cables and associated CPD.

  • Identification of cable cores.

  • Support and fixings.

  • Connections and enclosures. Check to confirm that cables are suitably terminated. e.g. under benches.

  • Underground wiring systems. Check installation method. Cat 1 etc.

  • Overhead wiring systems. Check clearances from structures, vegetation and ground.

  • Segregation from other services. Gas, water, solar.

  • Protection against external influences. e.g. mechanical damage, effects of UV light.

  • Installation of cables in accessible areas of the ceiling space. e.g. near manhole, crossing roof battens and trusses.

Electrical Equipment

  • General condition of electrical equipment.

  • Isolation devices installed where required.

  • Isolating device for range installed within 2 metres of the hob.

  • Down lights installed in accordance with the wiring rules.

  • Equipment installed as per manufacturers requirements. e.g. anti-tilt bracket for upright range.

  • Fixing and support of equipment adequate

  • Equipment suitable for the operating environment. e.g. IP rating.

  • Protection against hazardous parts. e.g. guarding, screening etc.

  • Availability of user manuals, operating instructions.

Earthing

  • Earth electrode installed. Painted and tag attached to main earthing conductor.

  • Earthing conductors. e.g. size, identification.

  • Equipotential bonding conductors. Pool fences, water piping, slab reinforcing wet areas

  • Connection, joints and terminations adequate.

  • Protection against external influences. e.g. mechanical damage, effects of UV light.

  • Conductive building materials connected to earth where required. e.g. contact with single insulated cables.

  • Creation of an earthed situation that may require earthing of additional electrical equipment.

Exit Checks

  • MEN connection intact

  • Switchboard secure.

  • Main switch and circuit protection returned to original state.

  • Manhole replaced.

  • Tools and equipment returned to vehicle.

  • Person in control advised of departure.
